This entire debate comes down to who is responsible for securing the Internet. Everybody wants to put security on someone else (to save money and face of course) but I believe that the carriers are responsible for security. As the gatekeepers of the Internet (and the people we pay to access it) they have the responsibility AND THE MEANS to secure against viruses, hackers, and DDos. Companies such as www.narus.com have successful and proven solutions to these things but the telcos are slow to adopt (due to cost and not wanting to admit responsibility). I have little sympathy for DDos and other Internet attacks. Considering the telcos can easily remedy these things, it is up to the customer base (users) to get carriers to adopt solutions and accept responsibility.
